DISPENSING-CAN.

Specification of Letters Patent.

Patented May 14., 1912.

To all whom; it may concern:

" rooted to the provision of a fluid containing can of such aconstruction that its contents may be ejected without tilting the can.

More specifically, our invention resides in the provision of an aircompressing device directly applied to the can and efiective whenoperated to introduce air under pressure into the tank of the can andupon the surface of the fluid for forcing such fluid outwardly through adischarge'pipe carried by the can.

Our invention further consists in the provision of a structure wherebythe compressed air within the can may be directly admitted to the pipeat a point nearer its upper end, thereby counteracting the normal effectof the air upon the body of the liquid within the tank. We preferablyaccomplish this by the provision of a valve in the discharge pipe at apoint just within the tank, the opening of such valve serving to admitthe air under pressure into the discharge pipe. In the embodiment ofthis conception, we desirably provide a valve structure which isautomatic in its nature. By this, we mean that the movement of theswinging discharge pipe to an operative position or rather to a positionbest suited for delivery of the fluid is utilized to close the valvestructure and thereby exclude direct admission of the air to the pipe.From this it will be understood that the swinging discharge pipe isnormally in inoperative position with its discharge orifice above thetop of the tank and with the valve structure opened to admit the airunder pressure directly to the discharge pipe to out off the flow offluid theret-hrough. We further provide an indicator forautomaticallydisclosing the level of the fluid within the tank, which indicator ispeculiarly constructed to comprise a reciprocating indicator elementmovable through the jacket of the tank which discloses any differentvolume of fluid within the tank by a greatly reduced travel.

Our invention further comprises various novel features of structurewhich will be hereinafter pointed out in the specification and definedby the appended claims.

The preferred embodiment of our invention is shown in the accompanyingdrawings in which similar characters of reference designatecorresponding parts and in which,

Figure 1 is a top plan view of our dispensing can in assembled conditionand showing the discharge pipe in its preferred position of operation,Fig. 2 is a side elevation of our dispensing can, Fig. 3 is a verticalsection of our assembled dispensing can, Fig. 4 is a view taken on lineH'of Fig. 3, looking in the direction of the arrows and showing thestructure of the float and connection for controlling the indicator,Fig. 5 is a vertical section of a valve structure mounted upon the tankof the can for releasing the air under pressure therefrom said valvestructure being incorporated into the cap for the filling opening of thecan, and Fig. 6 is a section taken on line 66 of Fig. 3 and showing thevalve structure carried by the dischargepipe.

In the drawings, our dispensing can is shown as comprising a tank 1having a carrying bail 2 of ordinary form and having its bottom providedwith a depression 3 with an upwardly extending pin 4. The discharge pipeshown comprising a vertical interior portion 5 resting in the depression3 and embracing the pin 4; It will be seen that this lower extremity ofthe pipe 5 which embraces the pin 4: is cut away as at 6. The upper endof the discharge pipe portion 5 is preferably shouldered or providedwit-h a shouldered sleeve 7 rigidly secured thereto, the said pipe andsleeve being apertured as at 8. Embracing the said sleeve and restingupon the shoulder 7 thereof is a collar 9 apertured as at 10 andextending through the upper wall of the tank. This sleeve 9 isstationary and the portion 5 of the pipe together with the shoulderedsleeve rotate therein being rigidly secured to and feeding the dischargenozzle 11. With reference to Fig. 3, it will be seen that the dischargenozzle 11 is in operative position and that the-apertures or ports 8 and10 are out of alinement. Movement of the discharge nozzle 11 into normalposition causes the ports 8 and 10 to aline and effect communicationbetween the interior of the tank and the pipe.

The indicator structure of our invention desirably comprises a float 12carried upon a concentric sleeve 13 depending below the float 12 andhaving cut away port-ions 13 to aline with the cut away portions 6 ofthe discharge pipe when the float is in lowermost position. The float 12is desirably embraced by a yoke 14 extending across the upper surfacethereof and embracing the sleeve 13 and downwardly bent at its extremityto form perforated ears 15. There is provided a bail 16 having a Telement for the support therefrom of a rod 17 loosely connected to andcapable of a telescoping action upon or within a lever element 18carried at its opposite extremity by a pivot bearing 19 secured to theinterior wall of the tank. The indicator proper comprises a rod 20pivot-ally secured upon the element 18 and extending vertically upwardthrough the upper wall of the tank and into a transparent casing or somesimilar" air tight casing 21, which casing may be suitably graduated. Ifdesired 1 may provide an antisplash member 22 in the form of a disk ofmetal stamped to concave form and centrally apertured for the passagetherethrough of the indicator 20. It will be observed from the abovedescription of our indicator structure that we have provided anindicator proper which is automatically movable into view from withinthe tank upon the rise or fall of the fluid contained therein, but thatthe length of the indicator disclosed is definitely and comparativelyreduced owing to the transverse telescoping lever comprised of themembers 17 and 18.

The air compressing device desirably utilized in our dispensing can isbest shown in Fig. 3 and comprises a main cup 23 having a centralaperture 2 1 and concentric spaced annular grooves 25 and 25 coactivelyforming an intermediate seat for an anti-splash cup 26 substantiallyidentical in form with the cup 22. The edge of this anti-splash cup 26fits within the space between the annular grooves, and the outer mainannular groove fits closely within the opening in the top of the can.Thus, it will be seen that there is provided a simple and air tightconstruction. Vithin the cup 26 and carried by the cup 23 is a one-wayvalve structure 27 comprising a stamped disk 28. Cooperating with thecup 23 is a diaphragm 29 of flexible material and having its outerperipheral edge clamped upon the edge of the cup 23 by a crimping ring30. This diaphragm is desirably clamped at its central area betweenplates 31 and 32 having relatively diverging peripheral edges andperforated for the passage of air therethrough and into a one-way valvecup 33, likewise comprising a stamped disk valve 34. The plates 31 and32 are desirably clamped together and maintained in position by a bridgemember 35 of stamped material and having a lug 36 extending through ahood 37 and pierced for the reception of an operating lever 38, shown inFig. 1, as being pivoted to a member 39. The filling orifice for thetank of our dispensing can is desirably closed by a cap 40 having itsupper wall apertured as at 4.1, which aperture is closed by a valve 42carrying a valve stem 43 and a button 14. This valve 42 is normallymaintained in position by a coil spring 415. i

In operation it will be understood that, considering it is desired todischarge oil from the can, the nozzle 11 is moved to operative positionand the lever 38 is operated to operate the diaphragm. This serves toforce air into the tank of the can under pressure which necessarilycauses the discharge of the fluid through the discharge pipe. If it isdesired to immediately shut off this discharge, the button 14 upon thecap 10 may be depressed to permit the compressed air to escape from thetank; or the nozzle 11 may be swung to normal position, which will causethe ports 8 and 10 to aline, thus permitting an influx of the air underpressure into the discharge pipe. Thus it will be seen that there areprovided two means for instantaneously cutting off the discharge offluid from the can. Further it will be seen that the float is raised orlowered in accordance with the volume of fluid in the tank and that suchraising or lowering of the float produces a Visual indication of thequantity of fluid in the tank. It will be further noted that theindication is effected by a reciprocable indicating rod having amovement comparatively small with relation to the movement of the float.It will further be seen that the air compressing device is constitutedof parts readily made and is further provided with a rigid crimping ringfor its peripheral edges together with clamping plates for the centralarea thereof which are calculated to avoid fraying of the diaphragm. Inaddition, it may be noted that applicants structure of bottom and lowerextremity of the discharge pipe together with the particular form of thesleeve 13 all serve to permit a removal of practically all the contentsof the tank. In more thorough explanation of this, it will be apparentthat the depression of peculiar form in the bottom of the can and inwhich rests the lower end of the discharge pipe is of such a nature thatpractically all of the fluid in the can gravitates into such depression.Thus, when the can is almost empty the fluid therein concentrates inthis depression and the discharge therefrom is facilitated by thecutaway portions in the lower end of the discharge pipe as well as bythe cutaway portions in the lower end of the journal sleeve, upon whichthe float is mounted. Actual experiment demonstrates that such astructure renders possible the discharge of substantially every drop offluid in the can.
